Packet 9: Bonus 14
The McCabe-Thiele method can determine the ideal number of theoretical stages to complete this technique. For 10 points each,
[10e] Name this technique in which a mixture is separated based on differences in components’ boiling points.
ANSWER: distillation
[10h] Two values of this quantity define the axes of a McCabe-Thiele plot. Raoult’s law states that the [read slowly] vapor pressure of a solvent in a solution equals this quantity for a solvent times the vapor pressure of a pure solvent.
ANSWER: mole fraction [prompt on chi]
[10m] On a McCabe-Thiele plot, chemical engineers often make use of a line named for this letter, which describes the condition of a feed entering a distillation column. A common equation relates a quantity symbolized by this letter equal to m-c-delta-T.
ANSWER: q [accept q-line; prompt on heat]
